Voronoi wall complete

Table of contents

The Green Façade is the first 3D concrete printed structure in Twente. It was realized through a cooperation between Saxion Industrial Design Research Group, De Witte van der Heijden Architecten, Vertico Large Scale 3D printing and Trebbe. Read the full story on the Voronoi Wall project page.

From research project to interior garden

In 2016, Saxion Industrial Design Research, with head lector Karin van Beurden, started RAAK KONKREET, a two-year research project on 3D concrete printing sponsored by SIA.

George de Witte of De Witte van der Heijden suggested creating the structure for the interior garden of the Stepping Stones building, realized by Trebbe. Iman Hadzhivalcheva developed the basic design under the project management of Ivo Vrooijink.

Designed to be stacked by two people

The final design was made with parametric modeling. Each piece has a unique form, fits on a pallet for easier transport and weighs under 50 kg, so two people can build the full structure by stacking the pieces on top of each other.

The 50 unique elements were printed with our large ABB robot arm and a gantry by Rohaco. The façade weighs approximately 2.5 tons. Trebbe managed transport and installation.

The project is an early example of how printed elements can form 3D printed façades and other building components in construction.

FAQ About the Printheads

Do I need an HMI for printing with Accelerated printhead?

Yes, an HMI (Human-Machine Interface) guides you through the entire 3D printing process with 2-component materials—from preparation to printing and cleaning. It provides real-time data from the printhead’s sensors, giving you full control over the printing process by monitoring key parameters such as accelerant pressure, material flow, etc.

What is the biggest advantage of the Accelerator Printhead compared to a standard one?

The Accelerator Printhead unlocks unparalleled design freedom, allowing for large overhangs, intricate patterns, and complex geometries—perfect for architecture and custom design. It also enables rapid curing, reducing production time while maintaining high precision and structural integrity.

What materials can be used with the Accelerator Printhead?

We have developed a high-resolution, stable material specifically optimized for the Accelerator Printhead. When you purchase a machine, we provide our material recipe free of charge for your local production. Additionally, you can use any suitable material available on the market, offering flexibility for different projects and requirements.

What software does Vertico provide, and is it included with the machine?

Vertico offers an advanced in-house slicer software, designed to handle even the most complex 3D concrete printing projects. Our software comes license-free with every machine purchase, along with full training to ensure you can maximize its potential.
